CAP OR STOPPER FOR- BOTTLES, GANISTERS, JARS, AND THE LIKE Filed April 6 329 UNITED STATES PATENT OFFICE WALTER FRANCIS YOUNG, OF SURREY, ENGLAND CAP OR STOPPER FOR BOTTLES, CANISTERS, JAR-S, AND THE LIKE Application filed April 6, 1929, Serial No. 353,075, and in Great Britain April 11, 1928.

This invention relates to caps or stoppers for bottles, canisters, jars and the like, of the kind comprising means whereby the said cap or stopper can be secured to the neck or rim of the bottle, canister, or jar in such a manner that it can be readily removed and replaced thereon, and the said invention provides means for sealing or fixing the cap or stopper to the bottle, canister, or jar so that after the cap or stopper has been initially closed and sealed it cannot be opened or removed without destroying the sealing or fixing means and thus giving an indication that access has been had to the contents of the bottle, canister or jar.

According to this invention, the cap or stopper is provided with a flange or band adapted to be secured to the neck or rim of the bottle by means of interengaging lugs provided upon the neck of the bottle and the flange. the said flange having a part or parts thereof adapted to be sprung into a recess or recesses in the bottle or jar to lock the cap upon the bottle.

The interengaging parts of the bottle and the flange may comprise a screw thread formed upon the neck of the bottle and in dentations or mutilated screw threads formed in the flange, and a strip or strips may be partly cut out from the material of the flange and partly attached thereto along lines of weakness, one end of the strip or strips being provided to be sprung inwardly to engage with a corresponding abutment or in a recess formed in the neck of the bottle to lock the cap upon the bottle. In a convenient constructional arrangement in accordance with the invention, the inwardly bent end of the 4 said strip may abut against one end of an interrupted screw thread formed on the neck of the bottle, the-said screw thread also serving to engage the indentations upon the flange as hereinabove mentioned. A seal may be provided to cover the said bent-in portion of the strip.

In the accompanying drawing Figure 1 is a side view of a cap and bottle constructed in accordance with theinven- 80 tion;

Figure 2 is a view similar to Figure 1, showing the cap in position on the bottle;

Figure 3 is a plan of Figure 2, and

F igures 4 and 5 are views similar to Figure 1, showing modified forms of the invention.

In the drawing, Figures 1 to 3, a cap or stopper a'constructed in accordance with this invention has a flange Z2 thereon formed With lugs or indentations 0 to engage with lugs or portions of an interrupted screw thread d upon the neck e of a bottle, canister, jar or the like 7. The said cap is moreover provided with a part 9 adapted to be pushed or sprung in or indented to engage a shoulder 5 h on or a recess in the bottle or jar. This indented portion 9 can be covered by a suitable seal (not shown) and can be in the form of a strip partly cut out from the material of the said flange or band and partly attached thereto preferably along lines of weakness 2' formed by perforating or indenting the said material. T 0 release the cap or stopper the said strip is torn off or broken from the flange or band thus breaking the seal and removing the above mentioned indented portion from the said recess. By cut ting slits in the flange or band 6 two tongues g, are provided close together extending in opposite directions. Two or more such pairs 5 of tongues can be provided around the flange or band. After the cap or stopper has been put in place on the neck or rim of the bottle, canister, or jar one of the tongues 9 can be sprung or pressed in to engage the'shoulder k on the bottle neck or rim and a seal can then be applied over this tongue. The other tongue j when it is desired to remove the cap or stopper can be readily bent up so that it can be grasped by the fingers or by a suitable tool in order that a pulling eflort can be exerted thereon to tear out the strip and thereby remove the locking tongue from the said recess. In this operation the seal'is broken. The cap may be provided interiorly with a as suitable washer or liner of cork, india-rubber or other resilient material.

A suitable seal may be made by the application of a coat of paint, by a paper band securedin position by means of an adhesive,

or by a crimped metal band covering the bentin tongue, or if desired, a recess or bead can be formed around the bent-in tongue to provide a seating for a fused metal or wax seal.

In Figure 4; the invention is shown applied to a bottle neck having a screw thread 61 comprising substantially one complete turn and terminating in a shoulder h. The screw thread may however comprise any convenient number of turns. The shoulder h instead of being formed on the screw thread cl can be formed on a bead k on the bottle neck (Figure 5).

I claim:

1. A ar provided with a lug upon the neck thereof, a stopper provided with a lug to engage the neck lug, a shoulder at one end of the neck lug, and a tongue extending in a circumferential direction around and part-.

1y cut out of the stopper to provide an end to abut against the said shoulder.

2. A jar provided with an interrupted screw thread upon the neck thereof, a stopper provided with lugs to engage the parts of the said screw thread, shoulders at the ends of the said parts and tongues extending in a circumferential direction around and partly cut out of the stopper to abut against the said shoulder.

3. A jar provided with a lug upon theneck thereof, a stopper provided with a lug to engage the neck lug a shoulder at the end of the neck lug, an inturned tongue on the stopper to engage the said shoulder and a second tongue in continuation of the first mentioned tongue.

4. A jar provided with a lug upon the neck thereof, a stopper provided with a lug to engage the neck lug a shoulder at the end of the neck lug, an inturned tongue on the stopper to engage the said shoulder, a second tongue in continuation of the first mentioned tongue A and a weak connection attaching the tongues to the sto per.
